Referring to the drawing wherein like numerals designate like parts, itcan be seen that numeral 5 generally refers to the recorder instrumenton which the keys 6 are mounted and on which the operating lever 7 ismounted in the usual manner. The mechanism of this recorder forms noparticular part of this invention, and it is to be understood that anywell known recording instrument of the calculating type can be employed,as the gist of the present invention resides in the means for securingsuch a device to a telephone instrument.

In Fig. 1, a split annulus 8 is provided, the ends of which are bentlaterally to provide lugs 9 through which an adjusting screw 10 can bedisposed. The annulus 8 is secured to the recorder 5 by a rivet or ascrew 11 and as is clearly shown in Fig. 1, the annulus 8 is provided atits upper edge portion with inwardly disposed lips 12 which are adaptedto bear against the base portion 13 of a telephone instrument as in themanner shown in Fig. 2.

Inwardly disposed lugs 14 are provided on the annulus 8 for engagementagainst the bottom or base side of the instrument and Serial No.535,727.

these also serve as rests for the telephone instrument.

WVhile the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter, and furthermore, thelocking feature involving the padlock 21, shown in Fig. 5, can be usedin conjunction with the other forms illustrated or in fact, any otherform or forms within the scope of the appended claim.

Having thus described my invention, what I claim as new is An attachingclamp for telephones of the upwardly tapering base type comprising atransversely split ring, adjustable fastening means between the ends ofthe ring, whereby the ring can be clamped to the base, said ring beingprovided at its upper edge portion with inwardly and upwardly extendingportions defining projections for engaging against a reduced portion ofthe said base and at its lower edge with inwardly disposed lugs forengaging the bottom of the base.
